The main interest of splitting patches or adding a cover letter it to have
a place to explain the changes. When you have several changes, they deserve
several patches to provide an accurate explanation. In such case, you may
need a cover letter to describe the global idea of the series. A cover letter
is also helpful for mail threading and acking all the series.
When you have only one change, one email is enough.

John, should we add this explanation in the contributing guide?
